Massive cystic ureteral diverticula in infancy
The Journal of Urology
|August 1, 1991
Insights
Mid ureteral diverticulum, a rare condition, caused massive abdominal distension in two infants. One case involved a scarred kidney, the other a duplicated urinary system, highlighting unique pediatric urology presentations.
Area of Science:
- Pediatric Urology
- Congenital Abnormalities
- Ureteral Diseases
Background:
- Massive abdominal distension in infants can stem from various causes, including urinary tract anomalies.
- Ureteral diverticula are uncommon outpouchings of the ureter, with mid-ureteral locations being particularly rare.
Observation:
- Two neonates presented with significant abdominal distension.
- Case 1: A 1-year-old boy with a mid ureteral diverticulum and a chronically scarred, atrophied kidney.
- Case 2: A female newborn with a mid ureteral diverticulum associated with a duplicated ureter system (upper pole).
Findings:
- This is the first reported instance of mid ureteral diverticulum presenting with massive abdominal distension in neonates.
- The condition was associated with distinct renal and ureteral malformations in both pediatric cases.
- The specific association with a duplicated system and scarred kidney is novel.
Implications:
- Highlights the importance of considering rare ureteral anomalies in the differential diagnosis of neonatal abdominal distension.
- Suggests a potential link between mid ureteral diverticula and other congenital urinary tract abnormalities.
- Underscores the need for further investigation into the embryology and clinical significance of mid ureteral diverticula in pediatric patients.
Abstract:
We report 2 cases of massive abdominal distension due to a mid ureteral diverticulum. In a 1-year-old boy the mid ureteral diverticulum was associated with an atrophied chronically scarred kidney. In a female newborn the diverticulum was associated with an upper pole ureter of a completely duplicated system. To our knowledge this type of ureteral diverticulum has not been reported previously.
